I've been to Scotland a few times and, although I haven't ever seen any Loch Ness monster, I have seen some seriously mega castles. I once wrote on my bucketlist 'to see all the castles in Scotland' and this might be as achievable as deep sea diving with great white shaarks.

 

Ride the Hogwarts Express. 

 

The Hogwarts Express is in fact a famous steam train, the Jacobite, taking passengers on a 135-kilometre journey through mysteriously misty lochs and the never-ending green hills of the Scottish Highlands. Not only can you book your own seat on the train, but you can book yourself into the very compartment where Harry Potter sat on his own journey to Hogwarts (well, when he wasn’t stealing Ron Weasley’s Father’s flying ramshackle of a car or jumping into fireplaces and onto the cobblestones lining Diagon Alley). All the Jacobite needs now is a food trolley to sell Bertie Botts Every Flavour Beans, Chocolate Frogs, Pumpkin Pasties, Cauldron Cakes and Liquorice Wands.
